The short version

  • Only Aras Innovator has a free tier, so it costs nothing to try first.
  • Each has a real cost: Aras Innovator aras publishes no prices at all, so you cannot sanity-check a quote against a list price and every negotiation starts from the vendor knowing more than you do.; Siemens NX siemens NX offers only a 30-day free trial with no published subscription or perpetual license price; buyers must go through a sales process to get pricing, per the vendor's own product page.
  • They diverge on capability: Aras Innovator covers Model-based configuration, Siemens NX covers Advanced CAD.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Aras Innovator

  • Aras publishes no prices at all, so you cannot sanity-check a quote against a list price and every negotiation starts from the vendor knowing more than you do.
  • The platform ships as a toolkit rather than a configured process, so a first implementation is typically a six to twelve month engagement with an integrator, and services frequently cost more than the first two years of subscription.
  • The Community Edition is capped at 50 named users, gets only annual releases and excludes Aras-performed upgrades, so it is a genuine free tier but a deliberately awkward place to stay.
  • Configuration flexibility invites over-customisation; organisations that model every local exception end up with a system only two internal people understand, which is the same trap they left their previous PLM to escape.
  • CAD connectors are not all equal in maturity, and some are excluded from the base subscription, so a shop standardised on a less common CAD tool should confirm connector scope in writing before signing.

Siemens NX

  • Siemens NX offers only a 30-day free trial with no published subscription or perpetual license price; buyers must go through a sales process to get pricing, per the vendor's own product page.

Answered from the vendors’ own pages

Aras Innovator: Is Aras Innovator open source?

No. The source is not open. The Community Edition is free of licence fee for up to 50 named users under a revocable licence, which is not the same thing.

Siemens NX: Does Siemens NX offer a free trial?

Yes, Siemens offers a 30-day free trial of both Designcenter CAD and NX CAM software that is fully functional. Users can get a hands-on feel for the software without any financial commitment before purchasing.

Source
Aras Innovator: Can I buy a perpetual licence?

No. Aras sells subscription only. If a perpetual PLM licence is a procurement requirement, Aras is out.

Siemens NX: Is NX free for students?

Yes, Siemens offers free CAD/CAM Student Edition access to Designcenter and NX for students and educators. Academic offerings are available for those in educational institutions.
